Question

A solution of h2so4 acid is labelled as 95 percent. What is the mass of this that must be diluted with water to get 5litre of solution containing of h2so4 per litre

Answer 1

1 litre of the diluted solution must contain 10g of H₂SO₄
∴ 5L of the diluted solution must contain 50g of H₂SO₄
the concentration of the acid = 95%
⇒ 95g of H₂SO₄ is present in 100g of the acidic solution
⇒ 50g of H2SO4 will be present = 50 * 100 / 95
                                                     =52.64g
